During sowing, the most important thing to remember about tramlining is to shut off Autostep before doing anything other than normal sowing or turning in headlands between bouts.

    RDA 400S Cleaning Figure 5.10 Figure 5.11 Figure 5.12 At regular intervals and at the end of the season, check that there is no seed or packaging debris stuck in the seed hoses or in the seed outlets on the distributor head. At the same time, check the function of the tramlining flaps.

  • Page 96: Storing The Drill

    Maintenance and service Storing the drill Figure 5.14 The drill should be stored indoors when not in use. This is particularly important because the drill contains electronic equipment. The electronic components are of very high quality and can with- stand a lot of moisture but we still recommend that the drill be stored indoors. The Control Box should be stored at room temperature during the winter and between seasons.

    RDA 400S Troubleshooting General information on troubleshooting Many of the functions of the drill are controlled by a series of electrical, hydraulic and mechanical components. A good way to exclude many of the sources of faults from the start is to first deter- mine whether the fault is electrical.
